He glances at his precision sports watch and sees that the temperature is -12.9 F. What is this temperature in degrees C Celsius ()?

Answer 1

ANSWER

$-24.9$

EXPLANATION

Given;

$-12.9F$

To convert to degree Celsius, we use the formula;

$\begin{gathered} \frac{5}{9}(F-32) \\ \\ \end{gathered}$

Substituting F;

$\begin{gathered} \frac{5}{9}(-12.9-32) \\ =\frac{5}{9}\times-44.9 \\ =-\frac{224.5}{9} \\ =-24.94 \\ \cong-24.9 \end{gathered}$
